A number has 2 tens and 15 ones. write the number in words
The correct answer and explanation is:
The number with 2 tens and 15 ones is 35, which is written in words as:
Thirty-five
Explanation (300 Words):
To understand how we get thirty-five from “2 tens and 15 ones,” we must break down the place value system and what happens when ones exceed 9.
1. Place Value Basics:
In our base-10 number system, every digit has a place value:
- The ones place represents single units (0 to 9).
- The tens place represents groups of 10.
So, 2 tens means 2 × 10 = 20
And 15 ones means 15 × 1 = 15
Now, simply add these values together:
20 (from tens) + 15 (from ones) = 35
2. Why 15 Ones Becomes 1 Ten and 5 Ones:
Normally, when counting in place value, if the number of ones is more than 9, we regroup.
- 10 ones = 1 ten
- So, 15 ones = 1 ten and 5 ones
This means that the original 2 tens and 15 ones actually become:
- 2 tens + 1 ten = 3 tens
- And 5 remaining ones
So we have 3 tens and 5 ones, which is 35.
3. Writing 35 in Words:
We express numbers in words using standard English conventions:
- 30 = Thirty
- 5 = Five
So, 35 = Thirty-five
We use a hyphen between “thirty” and “five” because that’s the correct format for compound numbers from 21 to 99 (excluding multiples of 10).
Final Answer:
The number is thirty-five.
It results from regrouping 15 ones into 1 ten and 5 ones, and adding that to the original 2 tens to get 3 tens and 5 ones—making 35.
